Mysterious. This is why I dislike dynamic SQL: you can't tell whether it's really going to work until you run it. All I can suggest is some debugging. I don't really like to encourgae the use of the Devil's Debugger, but you can change the inner loop to show which column it's about to execute and hence try to figure out what goes wrong when it fails....
